I have a SONY DSLR-A200 camera that takes blurry photos unless the subject is perfectly still. In my manual, under selecting the flash mode, it says: Slow Sync, and then to the left of these words it the flash symbol with the word "SLOW" under the flash symbol. Beside that it says, "Fires whenever the built-in flash pops up. Slow sync shooting allows you to shoot a clear image of both the subject and the background by slowing the shutter speed." Any help would be appreciated!
